Finding the right coworking space for you isn't like choosing a product to buy based on specs and reviews - yes, all those basic facts (location, size, perks) matter, but often times it takes visiting the space itself and trying it out to see if it's really a good fit for you.

Below is a list of all the spaces in the CASC alliance and details about each. If you want to plan a visit to any of these spaces, give them a heads up using their "Book Your Visit" form.
